阿波番茶 (Awa Bancha)

Awa Bancha is one of only ~3 post-fermented Japanese teas; Kamikatsu's Zero Waste positioning anchors sustainable / heritage retail storytelling.
Caffeine very low (0.5-1.5%); polyphenol 8-15%; lactic-acid fermentation produces distinctive tartness and aroma profile.
Boutique tea retail, sustainable-positioned beverage, hospitality-amenity sets.
Post-fermented tea (post-fermentation distinct from oxidation) produced in the mountainous Awa region of Tokushima. Like goishi-cha, awa-bancha is a rare lactic-acid-bacteria-fermented tea — one of only a handful in Japan. Production by small Awa-region producers in Naka and Kamikatsu involves boiling fresh leaves, pressing into wooden barrels for fermentation, then sun-drying. The brewed tea is markedly low-caffeine, with a distinctive sour, fruity profile. Niche but with substantial collector and natural-fermentation following internationally; Kamikatsu's 'Zero Waste' branded version commands premium pricing.
